Buckyballs on DNA for harvesting light

Organic molecules that capture photons and convert these into electricity have important applications for producing green energy. Light-harvesting complexes need two semiconductors, an electron donor and an acceptor. How well they work is measured by their quantum efficiency, the rate by which photons are converted into electron-hole pairs.

Red light put moths in the mood

Do you dim the lighting and turn on the red light for a romantic night in with your partner? It turns out moths aren't so different in that regard. A new study published in Frontiers in Genetics shows that dim red light boosts sexual activity in a model species, the yellow peach moth Conogethes punctiferalis (family Crambidae), by selectively activating a genetic pathway related to olfaction in the antennae. This pathway ultimately makes males more sensitive to the odor of the female sex pheromone and thus more motivated to mate.

Incarceration is strongly linked with premature death in US

An analysis of U.S. county-level data found a strong association between jail incarceration and death rates from infectious diseases, chronic lower respiratory disease, drug use, and suicide, in a new study by Columbia University Mailman School of Public Health. The researchers found this was the case to a lesser extent for heart disease and cancer. The study is the first to examine the link between the expansion of the jail population and multiple specific causes of death at the county level, and adds to the growing body of evidence suggesting that decarceration strategies would improve public health. Findings are published online in the journal Lancet Public Health.

Imec demonstrates 20-nm pitch line/space resist imaging with high-NA EUV interference lithography

Imec reports for the first time the use of a 13.5-nm, high-harmonic-generation source for the printing of 20-nm pitch line/spaces using interference lithographic imaging of an Inpria metal-oxide resist under high-numerical-aperture (high-NA) conditions. The demonstrated high-NA capability of the EUV interference lithography using this EUV source presents an important milestone of the AttoLab, a research facility initiated by imec and KMLabs to accelerate the development of the high-NA patterning ecosystem on 300 mm wafers. The interference tool will be used to explore the fundamental dynamics of photoresist imaging and provide patterned 300 mm wafers for process development before the first 0.55 high-NA EXE5000 prototype from ASML becomes available.
